Induction of apoptosis in HT29 human intestinal epithelial cells by the cytotoxic enterotoxin of <i>Aeromonas hydrophila</i>
Bibliographic record
Abstract
The cytotoxic enterotoxin produced by Aeromonas hydrophila is considered to be the main virulence factor in gastrointestinal infections mediated by this pathogen. In this study, we examined the morphological and apoptotic effects of this toxin on HT29 cells, using light and electron microscopy in situ, as well as agarose gel electrophoresis of cell DNA. Cells treated with the cytotoxic enterotoxin became round and lost their polarity as well as their adhesion to each other and to the substrate. Cytoplasmic blebbing and nuclear condensation also occurred. DNA fragmentation was detected by TUNEL labelling and agarose gel electrophoresis. These results show that the cytotoxic enterotoxin of A. hydrophila can induce apoptosis in human intestinal cells in culture.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
